SNAP-HOOK.

Specification of Letters Patent.

Patented Mar. 9, 1920.

Application filed July 25, 1919. Serial No. 313,266.

To all whom it may concern:

Be it known that I, ALBERT BRUHN, a citizen of the United States,residing at St. Bonifacius, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Snap-Hooks; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in snap-hooks and has for itsobject to provide such a hook as will release the members which itconnects under excessive strain. he improved snap-hook is intended forgeneral use, but especially adapted to connect the trace carriers of aharness to the hip straps whereby, in case a horse kicks over thetraces, the snap-hook will release the connected parts before theharness will break and thus prevent damage to the harness.

To the above end, generally stated, the invention consists of the noveldevices and combinations of devices, hereinafter de-.

scribed and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Figure 1 is a perspective view of the improved snap-hook connecting astrap and ring;

Fig. 2 is an edge elevation of the same;

Fig. 3 is a plan view of the improved snap-hook; and

Fig. A is a transverse section taken on the line 4-4 of Fig. 1.

As shown, the improved snap-hook is formed from a single piece of springwire, intermediately folded upon itself to form the body 5. One end ofthe wire is bent to form the tongue 6 which extends from the undersideof the body 5, at the rear end thereof, upward between the members ofsaid body and normally and ieldingly rests on the transverse portion ofthe front end of the body 5. The other end of the wire is bent to forman attaching loop 7 and after completing said loop is twisted at 8,around both members of the body 5 and the tongue 6 to connect theseveral members of the improved snap-hook. While the attaching loop 7 isshown as of rectangular form, it may of course, be made in variousdifferent shapes.

Both members of the body 5 are bent downward to afford a transverse ringseat.9, that is oblique to the line of pull and over which ring seat thetongue 6 extends. As shown, a strap Y is attached to the loop 7 and aring Z rests in the ring seat 9 and is yieldingly held therein by thetongue 6. Obviously, an excessive pullon the ring Z will cause said ringto be cammed out of the oblique ring seat 9 against the tension of thetongue 6 and thereby release said ring from the snap-hook.

What I claim is:

l. A snap-hook arranged to release bya longitudinal pull under excessivestrain and return to normal position. a

2. A snap-hook having a ring seat, and a tongue extending over said ringseat and arranged to release by a longitudinal pull under excessivestrain and return to normal position.

3. A snap-hook having a ring seat that is oblique to the line of pull,and a tongue extending over said ring seat and arranged to release by alongitudinal pull under excessive strain and return to normal position.

4-. A snap-hook formed from a single piece of spring wire that isintermediately bent upon itself to afford a body, one end of said wirebeing bent to form a tongue normally and yieldingly overlying the outerface of the transverse portion of the front end of said body, the otherend of said wire being bent to form a retaining loop and thereafter bentaround the members of said body and tongue to connect the severalpartsof the snap-hook.

5. A snap-hook formed from a single piece of spring wire that isintermediately bent upon itself to afford a body, the members of saidbody being downwardly bent to afford a ring seat that is oblique to theline said body and tongue to connect the several of pull, one end ofsaid Wire being bent to parts of the snap-hook. 10 form a tonguenormally and yieldingly over- In testimony whereof I aflix my signaturelying the outer face of the transverse porin presence of two Witnesses.
